Like Pat said, forget bullseye. You should concentrate on a small spot. Orange dots about 1" in circumference can be pasted on your target, get em' at wally world. Also deer dont have orange spots. When you can put 6 arrows around em or in 'em you dont need em dont put em' on and shoot for 1st arrow you fire. Like he said 8" group is good. Practice from different positions, standing ,bent over, kneeling etc and start slow and then get faster an faster still with good form. IMHO you have 3-5 secs to get a shot off, animals dont stand still fer ya. I hunt from ground so if stand huntin maybe your time frame is longer.........bob
